Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside ...

Scientists find that close interactions between the mechanical properties of tissues and biochemical signalling between cells ...

Tiny plastic particles, from the micro- to nanoscale, have been routinely detected in water, soil, air, aquatic species, and humans in recent years. As concerns grow over their potential impact on the ...

Polystyrene nanoparticles are widely used in packaging, but their effects on organisms are unclear. Very little was known about how they affect blood cell development until now. Red blood cells are ...

A new advance in animal husbandry involving a popular aquarium fish should speed the pace of discovery in laboratory studies ...

While humans can regularly replace certain cells, like those in our blood and gut, we cannot naturally regrow most other parts of the body. For example, when the tiny sensory hair cells in our inner ...

Scientists identify specific genes involved in zebrafish sensory hair cell regrowth, providing new insights that could inform future research into hearing loss treatments. While humans can regularly ...

In vertebrate retinas, specialized photoreceptors responsible for color vision (cone cells) arrange themselves in patterns known as the "cone mosaic." Researchers at the Okinawa Institute of Science ...
